The problem can be solved by arranging different damping devices to reduce the probability that the barrel assembly impacts the box body in the washing process, enhance the anti-deviation capability of the barrel assembly and particularly reduce the vibration when the low-speed over-resonance point occurs.

Further, the projection of the washing tub 200 in the horizontal direction covers the projection of the sump chamber 400 in the horizontal direction. The projection of the washing tub 200 in the horizontal direction covers the projection of the water collection chamber 400 in the horizontal direction, so that the interval between the water collection chamber 400 and the cabinet 100 is increased, the collision of the water collection chamber 400 to the cabinet 100 is prevented, and the damage of the water collection chamber 400 is reduced; meanwhile, the water collecting chamber 400 is small, which is more convenient for installing other devices at the bottom of the box body 100.

The projection of the washing tub 200 in the horizontal direction may also be smaller than the projection of the water collecting chamber 400 in the horizontal direction, and more water can be collected.

Further, a drain pipe 401 is provided on the mounting plate 500, one end of the drain pipe 401 is communicated with the water collecting chamber 400, and the other end is communicated to the outside of the washing machine or with a general drain pipeline of the washing machine to drain water. By arranging the drain pipe 401 for draining the water in the water collecting structure in the water collecting cavity 400, after the water is drained into the water collecting cavity 400, the water in the water collecting cavity 400 is drained through the drain pipe 401, and the overflow of the excessive water in the water collecting cavity 400 is prevented.

Further, a first drain port 201 and a first drain pipeline 202 communicated with the first drain port 201 are arranged on the wall of the washing tub 200, and a water outlet 203 of the first drain pipeline 202 is arranged above the upper opening of the water collecting cavity 400. The first drain ports 201 and the first drain pipes 202 are plural, each first drain port 201 is respectively communicated with the corresponding first drain pipe 202, or plural first drain ports 201 correspond to one first drain pipe 202, when the washing machine performs a spin-drying process, water thrown away by the centrifugal action of the washing tub 200 enters the first drain pipes 202 through the first drain ports 201 and is discharged into the water collecting chamber 400 through the water outlet 203 of the first drain pipes 202, thereby preventing water from overflowing everywhere.

The water outlet 203 of the first drain pipe 202 is disposed above the upper opening of the water collecting chamber 400. By communicating the water outlet 203 with the water collecting structure, water enters the first drainage pipeline 202 through the first drainage port 201 during spin-drying and then is discharged into the water collecting cavity 400 through the water outlet 203, so that the water is prevented from overflowing; the water outlet 203 is arranged above the upper opening of the water collecting cavity 400 surrounded by the water retaining ribs 501, water discharged from the water outlet 203 directly falls into the water collecting cavity 400, the structure is simpler, other additional parts do not need to be added, and the water collecting effect is better.

Further, the washing tub 200 further includes a second water discharge port 204 for discharging water in the washing tub 200 into the water collection chamber 400 during dehydration and/or spin-drying, and a blocking device is disposed between the second water discharge port 204 and the water collection chamber 400, the blocking device opens the second water discharge port 204 during dehydration and/or spin-drying, a large amount of water in the washing tub 200 is discharged through the second water discharge port 204, the second water discharge port 204 is blocked during washing, and the water is retained in the washing tub 200 for washing.

Further, the second water outlet 204 is disposed above the upper opening of the water collecting chamber 400, and the blocking device is disposed at the lower portion of the second water outlet 204.

By arranging the second water outlet 204, when dewatering and/or spin-drying, the blocking device opens the second water outlet 204, water in the washing tub 200 is directly discharged into the water collecting cavity of the water collecting structure, the water blocking rib 501 blocks the water to prevent the water from overflowing, and the water is discharged out of the washing machine through the water discharge pipe 401; when washing, the second water outlet 204 is blocked by the blocking device, so that the water in the washing tub 200 is retained in the washing tub 200 for washing.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
